Luke and Jan Valentine were the Freak vampire brothers who invaded Hellsing during a Round Table conference, attempting to kill all inside. However, they met with unexpected resistance with Walter, who first reveals his wire-throwing abilities in Order 6 and Seras. Luke meets his end at the hands of Alucard, while Jan sets himself on fire after Integra shoots him.

Yan Valentine

Info: Younger of the two Valentine brothers.

Swears a lot, and loves blood and coke (the drink), he likes to shock people,

and speaks very loudly. Main attacker of Hellsing mansion.

He leads an army of ghouls into the building to kill anyone and everyone who stands in the way.

The Younger of the two valentine Brothers, Yan is loud mouthed, big talking, and punkish. It is not common to hear this boy cussing constantly about one thing or another, alot of which seems to be for attention. Jan is the more vicious of the two both in verbal and physical mannerisms. Leading the raid of ghouls upon the Hellsing Manor and straight into the house Yan could was quite happy with the violence, death, and chaos around him as long as blood was on the way. He met his death at the feet of Integral Wingates Hellsing after being shot with mercury bullets squarely in the head. This did not kill him however, he instead burst himself into flame and turned into a pile of ash.

Luke Valentine

Info: Older brother of the two Valentines, and leader of the two. Classy and arrogant,

he takes pride in his tactics and superhuman speed.

He and his brother attack Hellsing mansion in order to test out Alucard's power.

Luke is the eldest of the two Valentine Brothers. Well groomed and socially sophisticated, he seems quite different from the grungy punkish attitude of his brother Yan.. A rather conceited Vampire, he has it in his head that he is as powerful if not more so than Alucard himself. Fast and versatile, Luke is a force to be reckoned with but finds himself just dog chow in comparison to Hellsing's No Life King.
